摘      要：The variational aspects of secondary calculations based on a method of moments (MoM) solution are investigated. These calculations exhibit a type of second-order accuracy, regardless of whether or not the operator being discretized is self-adjoint, and regardless of whether or not testing functions are identical to the basis functions (Galerkin s method). Numerical results support these conclusions and suggest that the advantage of Galerkin s method in actual calculations is grossly overstated.
